The current density was raised sequentially from 0.5 A cm−2 during the first 240 h of operation to 0.75 A cm−2 for a further 1000 h. After operation, the (La,Sr)(Co,Fe)O3-δ (LSCF) cathode layers were analyzed with respect to Cr interaction by both wet chemical and microstructural methods. For cells equipped with interconnects coated with a dense APS protection layer, the amount of Cr on the cathode was in the range of a few μg. For cells with a porous WPS coating on the interconnect, the amount of Cr was in the range of 110–160 μg cm−2 and Cr-containing phases were detected by SEM analysis both on top of the cathode layer and also at the LSCF/GDC interface, which has rarely been observed before. In addition, a deterioration of the cathode microstructure near the LSCF/GDC interface was observed. With respect to the high current density during operation, a theory was developed which explains both the Cr deposition at the LSCF/GDC interface and also the deterioration of the cathode. 000830443 536__ $$0G:(DE-HGF)POF3-135$$a135 - Fuel Cells (POF3-135)$$cPOF3-135$$fPOF III$$x0 000830443 536__ $$0G:(DE-Juel1)SOFC-20140602$$aSOFC - Solid Oxide Fuel Cell (SOFC-20140602)$$cSOFC-20140602$$fSOFC$$x1 000830443 536__ $$0G:(DE-Juel1)HITEC-20170406$$aHITEC - Helmholtz Interdisciplinary Doctoral Training in Energy and Climate Research (HITEC) (HITEC-20170406)$$cHITEC-20170406$$x2 000830443 7001_ $$0P:(DE-Juel1)166023$$aYin, Xiaoyan$$b1$$ufzj 000830443 7001_ $$0P:(DE-Juel1)129636$$aMenzler, Norbert H.$$b2$$ufzj 000830443 7001_ $$0P:(DE-Juel1)130979$$aSpatschek, Robert$$b3$$ufzj 000830443 7001_ $$0P:(DE-Juel1)129591$$aBram, Martin$$b4$$ufzj 000830443 773__ $$0PERI:(DE-600)2002179-3$$a10.1149/2.0051710JES$$n10$$pF3028-F3034$$tJournal of the Electrochemical Society$$v164$$x0013-4651$$y2017 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.pdf$$yOpenAccess 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.gif?subformat=icon$$xicon$$yOpenAccess 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000830443 8564_ $$uhttps://juser.fz-juelich.de/record/830443/files/J.%20Electrochem.%20Soc.-2017-Beez-F3028-34.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000830443 8767_ $$84123511041528$$92017-06-07$$d2017-06-07$$eHybrid-OA$$jOffsetting$$lOffsetting: ECS$$pJESP-17-1453R 000830443 909CO $$ooai:juser.fz-juelich.de:830443$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000830443 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)165688$$aForschungszentrum Jülich$$b0$$kFZJ 000830443 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166023$$aForschungszentrum Jülich$$b1$$kFZJ 000830443 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129636$$aForschungszentrum Jülich$$b2$$kFZJ 000830443 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130979$$aForschungszentrum Jülich$$b3$$kFZJ 000830443 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129591$$aForschungszentrum Jülich$$b4$$kFZJ 000830443 9131_ $$0G:(DE-HGF)POF3-135$$1G:(DE-HGF)POF3-130$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lSpeicher und vernetzte Infrastrukturen$$vFuel Cells$$x0 000830443 9141_ $$y2017 000830443 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000830443 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000830443 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000830443 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ ELECTROCHEM SOC : 2015 000830443 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000830443 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000830443 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000830443 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000830443 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000830443 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000830443 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000830443 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000830443 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x0 000830443 9201_ $$0I:(DE-Juel1)IEK-2-20101013$$kIEK-2$$lWerkstoffstruktur und -eigenschaften$$x1 000830443 9801_ $$aAPC 000830443 9801_ $$aFullTexts 000830443 980__ $$ajournal 000830443 980__ $$aVDB 000830443 980__ $$aUNRESTRICTED 000830443 980__ $$aI:(DE-Juel1)IEK-1-20101013 000830443 980__ $$aI:(DE-Juel1)IEK-2-20101013 000830443 980__ $$aAPC 000830443 981__ $$aI:(DE-Juel1)IMD-1-20101013 000830443 981__ $$aI:(DE-Juel1)IMD-2-20101013
